Abstract
Compounds containing two cyclic hydrocarbon moieties which are substituted to provide crosslinking functionality and which are linked to each other by secondary or tertiary oxycarbonyl containing moiety are basis for compositions which are cured to provide cured thermosets for encapsulation and underfill for electronic components that are thermally decomposable to allow repair, replacement, recovery or recycling of operative electronic components from assemblies that are inoperative.
